To all whom it may concern: 7

Be it known that I, ALEXANDER It. PIPER, of Brooklyn in the county of Kings and in the State of New York, have invented a certain new and useful Improvement in Dumpin -Vehicles, and do hereby declare that the to lowing is a full, cleaii, and exact description thereof.

My invention relates to an improvement 1c in dumpin vehicles of any character, but

more especlally dumping cars. Inaccordance with the principles of my invention,

I have found it desirable to provide a car with a vertical elevation as small as possible and so constructed that the material carried in the car body can be readily and quickly dumped from the car and at as great a distance as possible from the car track.

More particularly, the object of my invention consists in letting the bolsters upon which the car body is supported into the body of the car itself so as to lower the center of gravity of the car and therefore the load carried thereby to as great an extent as possible, and also to lower the entire vertical height of the car so as to create a greater clearance when-the car is hauled through tunnels or under other overhead obstructions.

A further object is to construct the dumping doors on the sides of the car so that a portion of the door, tie, the lower art thereof, will be adapted when open to orm an extension of the floor of the car for the urpose of depositing. the material being amped from the car as far from the car track as is possible. I also so construct the upper side doors, that is to say, the doors w ich are located above the lower doors con- 40 stituting when open an extension of the car floor, so that t iese upper doors are supported in such a way that the greatest pos- 'sible clearance is obtained for the escape of the material being unloaded.

A further important feature of m invention consists in the manner in whic I construct the particulai' attachments for allow. ing the car body to'receive a jolt at the downward end of its path so as to more 5o effectively loosen up and discharge the material being unloaded.

Figure 1 is a side elevation of a portion of the dum ing car; Fig. 2 is a transverse section of t e same; Fig. 3 is a vertical elevation partly in section of the clutch mechanism; 4 is a plan view of-aportion of the interlocking mechanism; Fig. 5 is an elevation of one of the rollers used for supporting the car body; Fig. 6 is a front elevation of a trigger arm used in the construction; and Fig. 7 is a side elevation of the same.

In the drawings, 1 is a car truck of any preferred type which is connected to the body supporting mechanism of the car by meansof a segmental track 2 for pernuttmg the car truck to turn when the car is proceeding around a-curve. Inasmuch as I provide my car 3 with two such trucks 2, one at either end thereof, the body supporting mechanism consists in the main of two longitudinal I beams 4 which extend from one end of the car to the other, at which points they are adapted to support the platforms 5 having the usual appurtenances such as a step 6, 'etc. The said I beams 4 are connected at their upperfaces by means of a se ries of triangular brackets 7, which are designed to support by means of the pivot pins 8 the bolsters 9 extending transversely of and supporting the car bodies 10, of which there are two on each car, a space being provided bet-ween the same in the center of the car for an additional platform, having located thereon a vertical stationary support 11 carrying a trolley connection at its upper end for the current carrying wire located along the route of the track. It will be noted that the bolsters are let into the interior ofeach of the car bodies at the ends thereof and alsoin the middle thereof. At these points the bolsters are covered by means of the inclined plates 12 so as to permit the load of material carried in the body of the car over the bolsters to readily escape when the same is tilted.

The tilting mechanism is constructed as follows :At the center of the car I attach to the lower edges of the longitudinal I beams 4 a depending bracket 13 designed to support an electric motor 14 upon each end of the central shaft 15 of which is located a worm 16. Each of these Worms is designed to mesh with a worm gear 17 which is carried upon a shaft 18. The latter shaft 18 also carries a gear 19 fixedly attached thereto which meshes in turn with a gear 20 loosely carried upon a shaft 21 which extends from one end of one of the car bodies 10 to the other. It will thus be seen that there are two such shafts 21 on either side of the car, each of which extends the length [handle of the lever 33.

of one of the car bodies 10. Eachshaft'21 carries at either end thereof a small drum 22 provided with the usual flanges 23. These drums are designedto be connected by .ineans-of chains 24 to-the car body 10 by means of sheaves 25 inthe ends of'bols'ters 9,. Each of the gears 20 which are located. on the shafts 21 is provided on its face which is nearest tothe; motor mechanism with a clutch member 26 which 1 to inter-lock with a complementary' ielutch member 27 splined to the shaft 21'.-f'. "The complementary clutch members 27 carry on their faces which are nearest to the motor mechanism pairs of L-shaped arms 28 which are designed to rotate in grooves 29 in the ends of clutch shipper sleeves 30, which are carried on the inner ends ofeach shaft 21 on eitherside of the car. Each clutch shipper sleeve 30 is provided on its periphery with crossed curved grooves 31 in which pins 32 carried by lever arms 33 are designed to slide. Each of .the lever arms 33,

- of which there are two, one on either side .of the car, has a narrowLsleeve 34 surrounding one of the "shafts 21 for the purpose of guiding and supporting the pins 32. The circular portion 34 is located between station' aryv guides 35 so as to maintain it in its proper position. A series of teeth-36 are located in an extension 3.7 on either side of the circular guides 35 which are desi ed to hold the lever in the proper positlon by means of a reciprocating rod 38 which is normally'spring pressed into the lowermost position and designed to be retracted into its uppermost position by means of an auxiliary hand lever 39 located in proximity to the It will thus be seen by this construction that when one of the levers 33 is moved to either end of its path, the clutch member 26 will be caused to move one of the complementary clutchmembers into contact with one of theclutch members carried by 1 the gears 20, which results in one of the gears 20 being connect-edso as to rotate with one of the shafts 21 and thereby tilt the car body through the agency of the chains 24. It will also be seen that by the movement of one of these levers in one direction, the car body at one end of the car will be caused to be tilted, while from the movement of the same lever in the other direction the re-- maining ear'bodywill be caused to be tilted toward side of the 'car. Furthermore, 'f'wheirbiice; one of: the. car bodies has been tilted tgg ibiieside ofthe car, the same can be 'res'tored-ftoY-its orig nal horizontal" position by the operation',ef ithe lever located at thelother side of theicarjso as to v restore the carhodyto its normal position.

Before the latterean' take place, however,

it will .be obvious that the lever which has been operated to movethe car body into a dumping position must necessarily be'moved so as to disconnect the clutch which effected this movemgiibefore the lever on the other 'side of'th'e car can befoperated to restore the car to its normal horizontal osition, z. e., when elther lever 1s In use tli other is locked in neutral position with both of its therewith. This is constructed as follows I attach to each of the levers 33 a horizontal rod 40 which extends from the lever, to which it is connectedby means of a pivot,

transversely of the car to the other side thereo f, where it carries a beveled shoulder 41 designed to retract a pin 42 carried in the stationary guide 35 and extending through the same to the body of the lever 33 which is provided with a hole to receive the pin when the lever is moved to its middle osition; 'Each of the levers 33.is

provide with a controlling rod such as that already described. The result of this arrangement is that .when the lever which has been moved-to tilt a car body to a dum ing position, is v then moved a ain to 1 s middle position to separate the c utch members, the. rod 40 pivoted to this lever will come in contactv by means of its beveled shoulder 41 with the spring pressed pin 42 so as to retract the same from thefopening provided in the bod of thelever located on theopposite side 0 the car'againstthe action of spring 43.' inv this position of the rod 40 is permitted spending pin 42 on the other side of the car cooperating with the first mentioned lever is allowed to spring into the opening eooperating therewith so as to maintain the first mentioned lever permanently inits middle position while the remaining lever can be operated to move the car body to its normal horizontal position. Each of the car bodies 10 is adaptedto slide to a certain extent at the lower end of its path when tilted so as to givethe car body and the load contained therein a sudden jolt for the purpose. of more efiectively discharging the material therefrom. For this purpose the car body 10 is supported by means of a series of rollers 44 upon the respective bolsters 9. In order to effect the jolting referred to and at the same time maintain the car body The other lever then not ' to be moved, and when this occurs the correin its central position, I provide each of the bolsters with vertical slots located at either end thereof which are designed to cooperate with the zigzag slots 46 situated in the U-shaped plates 47- carried by the car body and fixedly attached thereto. Pins 48 are designed to extend through thesaid slots 45 and 46 so that when the car is in its horizontal and middle position, the said pins 48 on either side of the car will'be located immediately in front of the shoulders 49 of the zigzag slots 46, thereby preventing the car from being moved to either side of,

its central position. I attach to each of the pins 48 at its center a trigger arm 50 which depends therefrom through the longitudinal openings provided within the bolsters 9. These trigger arms 49 and 50 are operated at the lower end of the path of the car body when moved into a tilting position, by contacting with the faces of bumpers 51 attached to the I beams 4. The bumpers 51 comprise polygonal brackets 52 which support the shafts 21, the brackets 52 having inclined faces 53 which support by means of springs 54 lates 55 adapted to receive the car he y when it has reached the lower end of its tilting movement. At the same time that the car contacts with the bumpers in this manner, the trig er arms 50 also contact therewith resulting 1n thepins 48 being pushed upwardly beyond the shoulders 49 on this side of the car. When this takes place the car body is allowed to slide own accord against drop in front of the' shoulders 49 so as to hold the car in its central position.

In order to insure that the car shall be maintained in its horizontal and central position in the event of any accident causing a breakage of any part of the tiltin mechanism, I provide each of the car b ies at the end thereof adjoining the car platform with safety catches 57 which are designed to cooperate with the pivoted catches 56 supported from the I beams 4 by means of pivots 58. When the car bodies are in their horizontal and central position the catches 56 are designed to over-lie and cooperate with the catches 57 so as to maintain the car bodies in this position. v

To insure that the catches. 56 shall be permanently maintained in cooperation in this manner with the catches 57 while the cars are being transported from point to point, I

' body, the upper consist of a horizontal portion 60 having a ing 62, at which point the horizontal portion is adapted to be withdrawn in a horizontal direction so as, to remove the said horizontal portion from its position across the path of movement of the catch lever 57. The said horizontal portion 60 has attached thereto a vertical extension 63,the purpose of which is to effect tlfemovement of the horizontal portion so as to bring the pin 61 into alinement with the. opening 62 and to withdraw the horizontal ortion from its socket and the pin throng the opening 62 to release the catch lever 57.

Each side of eachof the car bodies 10 is provided with a air of doors, an upper door 64 and a lower oor 65. The up er door is suspended from a tie rod 66 an a tie rod 67, each of the tie rods extending along the upper edge of the side of the car body from one end thereof to the center of the side edge, where it is provided with a screwthreaded end 68 for securing it within a screw-threaded sleeve 69 located at the center of the car body. The said suspension dumped from the car body as far to one side of the car track as possible. I effect this by attaching the lower car door to the car body by means of eyelets 73,and chains 74 attached thereto at one end and at the other end to the car body by means of pins 75. The doors 64 and 65 are both designed to be secured in their closed positions by means of common fastenings 76 which consist of plates 77 attached to the lower door at the middle and two ends thereof, havin openings 78 for the passage of horizonta bars 79 having openings to receive chain supported pins 80 bars 79 being attached to the two end walls and the central partition of the car body. It will thus be seen that in closin the side doors of the car and then the lower door is raised by hand and when closed retained in this pos1tion by means of the pins 80. The lower door when I support the lower door when in its oor is closed by gravity so retained in its' closed; position also retains the upper door in its closed position because of the factlthat the'plates'f'i' extend sleeve 82- terminating in a hinge eye 83 in-- closes an extension and compression rod 84,

terminating in a hinge eye, 85, which hinge eye is held by hinge in 86. The stanchion 8 is attached'to the ongitudinal I-beams 4 of the car, and at each end gives a fixed bearing for the compression rod 84 through its eye 85 on pin 86.

In the operation of tilting the car body 10, the pivot 67 approaches the-pivot 86, thereby bringing the com ression bar 84 in contact with'the inner ten of the sleeve 82. at the eye 83, pushing the eye 83 against the pin 81,"and forcing; the door 64-.to open, as undicated in Fig; 2. When the car body is 'tilted up, the point 67 moves away from the sipoint 86, and no pressure is transmitted from an; pi-n. 81 to the mitted to close. i

In the operation of the dumpin mechanism, t -he pins 59 are rotated unti the pins pin 86, andthe door is per- 61 attached'to the horizontalmportionsthere- ,of come in alinement'with the openings 62, when the said pins 59 are withdrawn from in front of the catch. levers 56. The said catch levers 56 are thenmoved out of cooperation with the catches 57 situated on the car body so. as to release the car and permit it to be moved to a dumping position. The lever 33 on the side of the car toward which it is desired .to dump the material carried thereby, is moved from its middle position so as to operate the clutch located nearest the car body which itis desired to dump. The lever 33 when so moved, re-

leases the spring pin 42 cooperating withthe lever 33 located on the other side of the car so as to lock it in its middle position during the time that the other lever 33 is being operated. Upon the clutch be-.

' ing operated'as abovestated the chains con- 'nected to the shaft on which the said clutch is situated are wound around drums 'provided for that purpose, which results in tilt- I ing the car body toward this sideof the car. The'car continues to tilt until it comes in contact with the bumper. plates 54 at which point the trigger arms '50 also come in contact with the said bumper plates'resulting in moving the pins '48 upwardly away from the shoulder 49 constituting a portion of the zigzag openin s .orslots 46. Upon the pins 48 being so re eased, the car body begins to slide downwardly and continues to so slide until the pins 48 come in contact with the inner ends of. the zigzag slots 46, at which point the car body and the load of material containedtherein repins 80 having been previously with rawn from the apertured bars 79 so as to unlock the side doors, and when the above mentioned jolt takes place, these doors have moved to their open positions, the lower door vhaving assumed a horizontal position constituting an extension of the floor of the car body to which it is attached. The effect of the sudden jolt is," of course, to loosen up the body-of material contained within the car so as to cause it to be removed as completely as possible and as quickly as possible from the car body. It will also be seen that because of the particular position "in which I support the lower doorwhile open, the material'being discharged Will be projected to a very great distance 'toone side of the car track, which is a greatydesideratum. The car. body having thus been tilted to its'lowermost position the lever 33 which has efi'ected this operation is moved. to its central position so as to disengage the clutch members. This results in releasing the in 42 from engagement with the lever 33 ocated on the other side of the car. The latter lever 33 can now 'be moved so as'to cause the engagement of the clutch members located on thls side of the car which are designed to operate the car body which has been tilted. At the same timethis resultsin the pin 42 being permitted to engage-the other lever 33, that is to say, the. one which has been initially operated so as to prevent the latter from being moved during the time, that the remaining lever 33 is being operated. The latter now having been movedto cause the clutch members cooperating therewith to become engaged with one another, the-car body is gradually raised to its horizontal and central position through the agency of the chains 24 cooperating with'the said clutch members.

the safety catches 56 and 57 will become automatically engagedv with one another'so as to retain the car in .its normal position for receiving and conveying a load of material. The ever 33 at this point which has efi'ected the elevation of the car to its nor-.

mal position, is now moved to its central position to disengage the .clutchmembers.

When now the chain supported pins 80 are inserted through the a ertured bar 79 so as to lock the doors in t eir' clwed 'ositions and the pins 59 are moved horizontally across the path of movement of the safety catches. 56, the car is again in itsproperly adjusted position to receive a new load of As soon as the car body has reached its horizontal and central position material to be conveyed to any desired I point.
